From personal experience (6 months in NZ), I would suggest that she do the scrappin' once she gets home. The weight of the scrappin' supplies and book, etc can add up fast. In my case, I didn't have the photos to scrap. Once I got them developed and had a look, I sent them to my parents to see, and they kept them all together for when I got back.
I think keeping a good detailed journal is a good idea. I'm glad I kept a journal. When I read it now it's hard to believe how much I've forgotten.
Angie is right about postcards...sometimes the weather doesn't cooperate when you're touring and it's tough to get a good shot, but postcards usually have the perfect shot :) It might be a good idea to save brochures and maps from the places she visits too. I saved everything, school reports (I was in 7th form when I was there), bus route schedules, photos of friends and events I attended, stamps, coins...everything... to help me remember what I did.
Something I didn't do that I wish I would have was pick up some scrappin' stuff made for the local market. It might be easier to find stuff for Germany in Germany than it is here.
In addition to writing everything in a journal, tell her to take LOTS of photos. I was glad I had my camera in my hand as soon as I got off the plane. Just the car trip from the airport to my host family's home offered many interesting shots and it helped me remember my very first impression of Auckland. Even so, there are things I wish I would have gotten photos of but didn't, like of the presentation I made to the school before I came back to Canada.
One other thing...she might want to keep track of anything you send to her. One of the best memories from my trip was the Oreos my Mom airmailed to me. They didn't have Oreos in NZ when I was there...those cookies were worth about $2.50 per cookie by the time they got there. LOL Best Oreos I've ever tasted.
That reminds me...food is another thing. I have a stack of recipies from my trip. Now if I could just get them to import L&P to Canada, I'd be set. lol
Wish her luck and a safe trip for me. I'm sure she'll have a blast : )
